During the construction of a new snippet (I noticed that when you first start the element is initialized by jquery properly and it works in my case a photo jquery slider). The problem is when I try to save the page. It seems that odoo save in the database the entire html code (including the snippet) and second boot initialization via javascript not unsuccessful because the html code is not the same. I probably lost an important step in the documentation for this problem. Please show me how you should do it properly. Often it has been clear enough.
